Why it's great: The best makeup brushes don't have to break the bank. When it comes to this $3 E.L.F. makeup brush, readers say they "can't recommend [it] enough." It's made with synthetic fibers, but users insist that it feels as soft as higher-quality, natural-hair brushes. One member calls it "the best thing since sliced bread."
